Einstein’s theory of general relativity predicted that the space-time around Earth would be not only warped but also twisted by the planet’s rotation. Gravity Probe B showed this to be correct. CREDIT: NASA

Space-time is smooth rather than foamy, a new study suggests, scoring a possible victory for Einstein over some quantum theorists who came after him.

In his general theory of relativity, Einstein described space-time as fundamentally smooth, warping only under the strain of energy and matter. Some quantum-theory interpretations disagree, however, viewing space-time as being composed of a froth of minute particles that constantly pop into and out of existence.

It appears Albert Einstein may have been right yet again.
